Sure, fair enough.

If you don't really want to use it, then I don't think you need to add
it. I was just wondering if it made a difference.

Correct. "Simultaneously" is a bit of an overstatement, typically today
it's implemented by TDM - if you have two interfaces with a connection
to an AP each, but on different channels, each interface would just tell
its AP that it's going to sleep, but instead hop to the other channel
and tell that AP that it woke up... etc.
